Federal Aviation Administration July 15, 2008 – Federal Register Recent Federal Regulation Documents

This notice announces revisions to (1) Chapter 4, Special Airworthiness Certification, Section 9 of the FAA Order 8130.2F, Airworthiness Certification of Aircraft and Related Products, (2) Advisory Circular (AC) 20-27G, Certification and Operation of Amateur- Built Aircraft (AC 20-27G is the result of combining AC 20-27F and AC 20-139, Commercial Assistance During Construction of Amateur-Built Aircraft), and (3), requests comments on the percentage of fabrication and assembly that must be completed by an amateur builder to obtain an experimental airworthiness certificate for an amateur-built aircraft. This action is being taken because the FAA has determined that the existing Order and ACs do not adequately state the required levels of fabrication/assembly or guidance on use of commercial assistance. As a result, the existing Order and Advisory Circulars require revision. The FAA is seeking comments on these revisions.
